vTo alZZ whom-it may concern:l Y y Beit-known that I, WILLIAMTUNSTILL, of Paterson, inthe county of Bassai'c, and State j of- New Jersey, have'invented, made, -and applied -to use a certain new and useful 'Improvement in BraidingMachines; and-I do reference being had to the annexed drawings, making part oi this speciiiation, wherein- Figure l is a front elevation of my machine. Fig.. 2 is a side elevation. Fig. 3 is a plan of the stopmotion lever. Fig. 4 isan elevation of 'one of 'the spools, with the stoplinotionl .weight applied thereto; and Fig. 5 isa plan of the takefup rollers. y 1 Similar marks of reference denote the same parts.

AIn machines for braiding much inconven` consequent upon the length of crossbelt re? quired from the horizontal shaft to the main vertical shaft of the machine. This is particularly the ease with machines for braiding the covering of Wire or springs for hoop-skirts, Ybecause a numberof said machines set in a row anddriven by a horizontal shaft' occupy much more room than is' actually reqnired'l'orthe-machinery itself, because the length of belt essential in practice causes the machine to be at some little distance from said main shaft# The nature of my said invention consists in the arrangement of a stopmiotionv lever and miter-gcars, located between the main vertical shaft of the machine and Athe main drivingshaft, in such a manner that 'the machine -is' rendered much more compact thanheretofore,A and 'greater regularity in the movemchts'is in? sured.

In the drawings, a is the frame of .the mais chine, adapted to receive a braiding-machine on each side, as seen in Fig. 2.

The spoolsv 3, Weights 4, andA stop 5 to the s'pool are all of the usual character, and the thread lholds up the Weight 4; but said weight falls if the thread breaks, andfb'y the Yprojectionsl at the bottom of the weight acts upon thestopflever k.

@one of pulleys 18 on the shaft o. This belt 17 has to act with a certain amount of friction' to' wind up the braided material. If too muchA frietionis appliedin consequence of .the belt being too Mgmt, the material will be unduly strained, particularly'when the spool is almost fulL''This friction has heretofore been regu lated by lacing up the belt to the required length. This is both troublesome/and difficult-.pn account of theshortness of the belt. .I'theifeforemount the shaft 16v in vertical slots in@ 'the standards 19 and apply set-screws 20 '20 below, whereby the tension and friction of the belt are adjusted with accuracy.

i To' l-aythe braided material upon the spools q uniformly and evenly, I employ the traverse.;- bar r, with a loop, 2l, to passfthe'- braided material, and this bar is actuated by the heartshaped cam s, lever-t, and rod t. This cam sf.'l is rotated by a wheel, w, and worm on the shaft n, driven bythe wheel w and `Wormen the 'main shaft b.

1u place of the beit 1, from the dfviglshaft tothe pulley on the ruiter-gear LZ, a spurwheel might be made use of .to gear into a similar' Wheelplaced on the main drivingv Vhat I claim, and desire to secure by Letters Patent, is K t The arrangement of the lever g, eaten-bar h, and stopmotion lever k, in combination with the mitergears d andf, as and` for the 'pui-rposes set forth.
